KoRn is the best "nu-metal" band, but most of that stuff sucks. Then again, what do you call bands like NIN, Tool, and Rage Against the Machine? Because those bands can kick some ass, Tool live is something that is never forgotten.
I like System of a Down. Are they really nu metal? What exactly is nu metal; the same thing as alternative hard rock? The only metal I've heard is from the 80s and I don't like most of it. I think a lot of today's hard rock can be categorized as nu metal and I don't think it sounds anything 80s metal. Maybe it shouldn't be called metal at all.
